Global climate change is projected to lead to an increase in both the areal extent and degree of aridity in the world’s drylands. At the same time, the majority of drylands are located in developing countries where high population densities and rapid population growth place additional pressure on the ecosystem. Thus, drylands are particularly vulnerable to environmental changes and large-scale env
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland
Aims: To compare growth variability of Scots pine (Pinus sylvestris L.) on different soil types, and to assess the potential of peat-soil pines for climatological and hydrological studies.Methods: We used extensive dendrochronological anal- yses to investigate temporal and spatial responses of pines growing on peat soils and mineral soils in three regions of Lithuania.Results: Significant correlatAimsTo compare growth variability of Scots pine (Pinus sylvestris L.) on different soil types, and to assess the potential of peat-soil pines for climatological and hydrological studies.MethodsWe used extensive dendrochronological analyses to investigate temporal and spatial responses of pines growing on peat soils and mineral soils in three regions of Lithuania.ResultsSignificant correlations wer

The study presents a hydrology concept developed to include lateral water flow in the biogeochemical model ForSAFE. The hydrology concept was evaluated against data collected at Svartberget in the Vindeln Research Forest in Northern Sweden. The results show that the new concept allows simulation of a saturated and an unsaturated zone in the soil as well as water flow that reaches the stream compar
Europe is one of the world's largest food producers, and climate change may pose a serious threat to food security in the region. In the present study, we assess the potential impact of climate change on the Colorado Potato Beetle (CPB), Leptinotarsa decemlineata (Say)-a severe pest of potato (Solanum tuberosum, L.). We also investigate the possible impact of climate change on the phenological dev
The scientific knowledge of climate change processes and their worrying future implications for human societies and natural systems has developed considerably during the last decade, but necessary adaptive actions by decision makers have so far been rather limited. There are several causes to this, such as a discrepancy related to the communication between climate scientists and end-users, and the
Syftet med nuvarande arbetet är att genomföra en klinisk fallstudie som utvärderar begreppet Dynamisk-ElectroEnhanced Chemotherapy ™ (D-EECT). Tio patienter med plavocellkarcinom, åtta med bröstcancer och fem patienter med var och en som presenterade en annan typ av tumör, infördes i försöken initierade av fem olika cancercentra. Alla patienter fick Bleomycin och 2-3 behandlingstider med IQWave ™ The aim of the present work is to perform a clinical case study evaluating the concept of Dynamic-ElectroEnhanced Chemotherapy™ (D-EECT). Ten patients with squamous cell carcinoma, eight with breast cancer and five patients with each presenting a different type of tumour, were entered in the trials initiated by five different cancer centres. All the patients were given Bleomycin and 2 to 3 treatme
Under 1680-talet trädde Sophia Elisabet Brenner fram som poet och blev snart känd och uppskattad för sina dikter vid olika tillfällen i livet. Tillfällesdiktningen var en flexibel genre som gav henne möjligheten att resonera om tidens aktuella frågor, till exempel kvinnans ställning i äktenskap och samhälle eller värderingen av det som var gammalt och fornt och det som var nytt. Hennes rykte spred
The study presents a method to evaluate the response of forest ecosystems to increased biomass extraction based on the integrated ecosystem model ForSAFE. It evaluates the effects of residue removal, intensification of thinnings and a shorter rotation period on a forest site in Southern Sweden. The evaluation includes multiple ecosystem indicators for productivity, carbon storage, wood production,
Forest soils are generally considered to be net sinks of methane (CH4), but CH4 fluxes vary spatially depending on soil conditions. Measuring CH4 exchange with chambers, which are commonly used for this purpose, might not result in representative fluxes at site scale. Appropriate methods for upscaling CH4 fluxes from point measurements to site scale are therefore needed. At the boreal forest resea
Biogenic Volatile Organic Compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the biosphere, where the amounts released depend on climatic factors such as temperature and solar irradiation. However, interpretation of leaf-level measurements is currently hampered by factors such as large within-genotypic variability, measurement height and time in the season. A campaign
This article deals with a comparison between Matilde Serao’s short story “Checchina’s Virtue” ( 1884 ) and the homonymous unpublished theatrical script written by Massimo Franciosa ( 1995 ), of which a summary is provided. The comparison between the source text and the adaptation draws on the debate about the narrativity of drama in which many scholars have engaged in the last decades: Richardson
Terpene emissions from the top-canopy layer (at 20 m) of one 118-year-old Norway spruce tree were measured between June and September 2013 using a branch chamber. Total terpene emissions varied from 0.05 to 332.5 μg gdw -1 h-1 with a peak in August. Monoterpenes dominated throughout the summer and on average accounted for 65% of the total terpene mass, followed by sesquiterpenes (29%) and isoprene
The contribution of forest harvesting to base cation losses and soil acidification has increased in recent years in Sweden, as the demand for bioenergy has increased and the sulphur deposition has decreased. Thus, new policy tools are required to evaluate the progress of the recovery from acidification, and as a basis for forest management recommendations. In this study we introduce and test a con
The integrated dynamic ecosystem models SAFE and ForSAFEVEG were used to estimate critical loads for nitrogen using different chemical and biological criteria, and attempting to account for possible effects of climate change. The study is based on a model application on a set of 640 sites earlier used for critical loads assessments in Sweden, focusing on the ecological effect of nitrogen pollution
